COVID-19: Testing

Get Free At-Home COVID-19 Tests

Every household in the U.S. can receive four free at-home rapid antigen tests by mail. Anyone with a residential address in the U.S. is eligible, regardless of immigration status.

To request the free tests, or for more information:

  • Visit (available in English, Spanish and Chinese), or
  • Call 800-232-0233 (TTY: 888-720-7489; several languages available)

The only personal information you will need to provide to get the tests is your name and mailing address. You can also choose to track your order by providing an email address.

Orders will ship in seven to 12 days and be delivered directly to your home.

Testing remains an important part of reducing the spread of COVID-19. All New Yorkers should get tested for COVID-19 if they have symptoms or were recently exposed to someone with COVID-19. If you test positive after taking a home self-test, call your provider or 212-COVID19 (212-268-4319) to be linked to care.

See below for more information about when to get tested, the types of COVID-19 tests available and how to interpret tests results, including what to do if you test positive or negative.

Find a Testing Site

There are many health care providers, pharmacies and government facilities, including mobile and pop-up testing sites, offering testing — often free — throughout the city.

Here are some resources to help you find a location near you:

When you go for a test, you will not be asked about immigration status.

At-home Testing

If you need to be tested for COVID-19 and cannot be tested by a health care provider, consider taking an at-home diagnostic test. Some at-home tests have you collect a nasal or saliva sample and send it to a laboratory, while others allow you to get results in minutes.

Be sure to carefully read and closely follow the manufacturer’s instructions. You can also watch the below online instructional videos provided by the manufacturers before taking the test.

Note: At-home test results may not be accepted for some purposes, such as school, employer or travel testing requirements.

General Guidance

When to Get Tested

Everyone should get tested:

  • Immediately if you have symptoms of COVID-19.

  • Five days after having close contact (being within 6 feet for at least 10 minutes over a 24-hour period) with someone while they had COVID-19.

  • Before and after attending a gathering, especially if you and others are not fully vaccinated, or are at risk of severe COVID-19.

  • Three to five days following travel.

People who have frequent in-person contact with others and are not fully vaccinated should consider getting tested weekly. This is especially true for people in close contact with others who are not wearing masks indoors.

People who are vaccinated should still get tested. The COVID-19 vaccines cannot cause you to test positive.

Retesting After a Positive Diagnostic Test

If you recently recovered from COVID-19, you should not get retested for COVID-19 for at least three months after your symptoms began or, if you had no symptoms, from the date you were tested. You may continue to test positive for COVID-19, even though you are no longer contagious. If you develop new symptoms, talk to your health care provider.

Types of Tests

There are several different types of tests, with some more reliable than others or providing different types of information. Your health care provider can help you decide which type of test is best for you based on the reason for testing, such as recent exposure, presence of symptoms or periodic testing.

Diagnostic Tests

Molecular Tests

Molecular tests (nose or throat swab or saliva test), such as PCR tests, are the most reliable way to test for COVID-19. They can detect the virus even if there is only a small amount in your system.

These tests look for genetic material from the virus that causes COVID-19 (SARS-CoV-2). They usually require the specimen to be sent to a laboratory, which is why it may take a few days to receive results. A unique process used at COVID-19 Express sites allow for molecular tests to return results usually within a few hours.

Antigen Tests

Antigen tests usually provide results faster than molecular tests but can be less accurate. These tests look for proteins on the surface of the SARS-CoV-2 virus.

Antigen tests usually can be processed in a health care provider’s office, rather than a laboratory, which is why they are less expensive and can return results quickly. However, they are more likely than molecular tests to return false positive test results (the test result is positive but the person does not have COVID-19) and false negative test results (the test result is negative even though the person has COVID-19). In certain cases, such as when a person is showing symptoms, health care providers may recommend a follow-up molecular test to confirm the results of an antigen test.

Antibody Tests

Antibody tests check the blood for signs that you have had the virus in the past. They require getting a blood sample through a finger stick or drawing blood from a vein in your arm.

An antibody test may not be accurate for someone with an active or recent infection or for other reasons.

An antibody test result should not be used to make any decisions about whether someone can work or attend school. Antibody tests for COVID-19 cannot be used to detect whether someone is currently sick or infected, or whether someone is immune to the virus.

Antibody tests are not recommended after vaccination. It is not known whether currently authorized antibody tests can determine the level of protection provided by a COVID-19 vaccination.

After a Test

If you test positive for COVID-19 through a diagnostic test, immediately separate yourself from others and contact your health care provider.

The NYC Test & Trace Corps can help you and your close contacts prevent the spread of the virus. If you cannot safely separate at home, you and those you may have exposed to the virus can qualify for a free hotel room.

You should stay isolated until all of the following are true:

  • It has been at least 10 days since:
    • You started having symptoms or
    • The date you were tested (if you did not have symptoms)
  • You have not had a fever for at least 24 hours without taking fever and pain-reducing medicines, such as Advil, Motrin, Tylenol or aspirin
  • Your overall illness has improved

If you develop trouble breathing, persistent pain or pressure in your chest, confusion, inability to stay awake, bluish lips or face, or any other emergency condition, call 911 immediately.
